Abuilding is being constructed. when completed, it will be 596 meters tall. it currently stands at 77% of this height. which is the best estimate for the current height of the building? 350 meters 400 meters 420 meters 450 meters

The best estimate is 450 meters

Step-by-step explanation:

step 1

Find the currently height of the building

Multiply the total height by the currently percentage

therefore

The best estimate is 450 meters

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
